This video shows the veteran prop tricking an unsuspecting wedding guest into taking part in a contest to test their lung power by blowing into Jenkins' special pipe contraption.

Jenkins shows his fellow guests how it's done before challenging the unfortunate man to blow into the pipe for as long as possible.

The eager contestant takes up the challenge - only to end up with his face (and expensive-looking suit) covered in a white talc-style powder.

The prank leaves the watching crowd in absolute hysterics, with the victim hanging his head in disbelief.

It's not the first time Jenkins' pipe prank has caught someone out, with our very own rugby correspondent Simon Thomas counting himself among previous targets at Taufa'ao Filise's testimonial dinner earlier this year.
